Underthesea is an open-source Python toolkit for Vietnamese natural language processing that has evolved into an agentic AI toolkit with multi-provider LLM agent support (OpenAI, Azure OpenAI, Anthropic, Gemini) using zero external dependencies. It combines Vietnamese NLP modules like word segmentation with a lightweight Agent framework built on Python stdlib.

Use cases

• segment Vietnamese text into words
• build an AI agent that talks to OpenAI or Claude without extra dependencies
• do Vietnamese NLP in Python
• switch between multiple LLM providers with one interface
• process Vietnamese text for chatbots
• run Vietnamese NLP in a Colab notebook

When to choose

• you need Vietnamese-specific NLP like word segmentation
• you want a dependency-free agent that calls LLM APIs with stdlib only
• you need multi-provider LLM support (OpenAI, Anthropic, Gemini, Azure)
• you want a mature, well-maintained Vietnamese NLP library

When to avoid

• you need NLP for languages other than Vietnamese
• you need a full-featured agent framework with tools, memory, and orchestration
• you need high-performance production LLM features like streaming or retries
